k8s创建redis集群
1.首先k8s要有StorangeClass,这里为data
新建redis-cluster.yaml文件
apiVersion: v1 kind: ConfigMap metadata: name: redis-cluster data: update-node.sh: | #!/bin/sh REDIS_NODES="/data/nodes.conf" sed -i -e "/myself/ s/[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}/${POD_IP}/" ${REDIS_NODES} exec "$@" redis.conf: |+ cluster-enabled yes cluster-require-full-coverage no cluster-node-timeout 15000 cluster-config-file /data/nodes.conf cluster-migration-barrier 1 appendonly yes protected-mode no --- apiVersion: apps/v1 kind: StatefulSet metadata: name: redis-cluster spec: serviceName: redis-cluster replicas: 6 selector: matchLabels: app: redis-cluster template: metadata: labels: app: redis-cluster spec: containers: - name: redis image: redis:6.0.6 ports: - containerPort: 6379 name: client - containerPort: 16379 name: gossip command: ["/conf/update-node.sh", "redis-server", "/conf/redis.conf"] env: - name: POD_IP valueFrom: fieldRef: fieldPath: status.podIP volumeMounts: - name: conf mountPath: /conf readOnly: false - name: data mountPath: /data readOnly: false volumes: - name: conf configMap: name: redis-cluster defaultMode: 0755 volumeClaimTemplates: - metadata: name: data spec: accessModes: [ "ReadWriteOnce" ] resources: requests: storage: 5Gi storageClassName: data #改成NFS的名称
执行命令: kubectl apply -f redis-cluster.yaml
执行命令查看: kubectl get all
3主3副的pod已经启动成功
执行初始化集群命令:
kubectl exec -it redis-cluster-0 -- redis-cli --cluster create --cluster-replicas 1 $(kubectl get pods -l app=redis-cluster -o jsonpath='{range.items[*]}{.status.podIP}:6379 ')
输入:yes

这个时候集群创建完成
